The Tesla Powerwall 2 is the successor to Tesla's first Powerwall. It is an AC-coupled battery system, including a 13.5kWh NMC lithium-ion battery pack and inbuilt inverter. The cells were designed by Tesla and Panasonic and are manufactured in the USA. The Powerwall 2 incorporates a liquid thermal regulation system to keep the batteries at an optimal temperature.
